I have posted regarding this before. About 4 months ago I introduced a new cat into a household with 2 resident ones. It has been a pretty smooth, but not perfect, introduction. She still swats, growls and hisses at the other two fairly often when they get too close. On the other hand, they share food bowls, litter boxes and sunny spots, chase toys and the birds outside together, and can be in the same room as long as they are comfortably separated or on different levels. So, I think it's going as well as can be expected.
My concern is that she still has not warmed up to me. She is very fussy about being petted or picked up or held, does not like being groomed, and will ocassionally swat, growl or hiss at me when I pet her (overstimulation, I guess). She doesn't hide from me, and actually will come out when strangers arrive, but she rarely seeks my lap out, and is not at all cuddly like my other two, unless I have food.
Might she just be a "cold fish" or require more time getting used to me? Her previous owner (she is 6) said she was a sweetheart, but I understand he hardly paid any attention to her and travelled a lot. I spend a lot of time with my cats and like to pay attention to them, so maybe she is not used to that.
